Delphi DCM3.5 ECU AV41-12A650-CH – what to know
Unit AV41-12A650-CH (Delphi 28298211) controls the 2.0 TDCi engine in Ford cars. We test every unit before sending it to the customer.
Numbers to compare with your label
The housing of the original ECU carries a sticker with its numbers. On this unit they are:
- Ford number: AV41-12A650-CH / AV4112A650CH
- Delphi number: 28298211
- ECU type: Delphi DCM3.5
How to check compatibility
The safest way is to compare labels. If your ECU shows number AV41-12A650-CH and number 28298211, it is the same version – whatever the Ford model and year, as this number may appear in different cars. If the sticker is hard to read or you have questions, send us a photo of it before buying.
When the ECU may be faulty
An engine ECU failure may show up as:
- no start and no signal at the injectors,
- the diagnostic tool cannot connect to the ECU,
- the ECU gets no power even though the fuses are OK,
- problems after water damage or a short in the wiring.
Faults in the wiring, power supply or sensors can cause similar symptoms, so run a diagnosis before you buy.
Preparation and fitting
- After purchase, send us your VIN – we prepare the ECU with data from the Ford server and the latest software. This service is included in the price.
- The ECU is not plug & play: after fitting it requires PATS programming (keys and VIN) with FORScan or Ford IDS.
- Warranty: 6 months.
